The set -x has produced 6 identical log strings every time the log_backup_error_exit function is called. Prometheus is using the occurrence and number of some logs over a period of time to evaluate database backup failure or not. Only one log should be generated when a particular database backup scenario failed. Upon discussion with database backup and restore SME, it is recommended to remove the set -x once and for all.
